Keiyaku-kon no Otto ni Motomeraretemasu

Princess Alexa Calenda knows she is nothing more than a quiet spoil of war to her husband. To her, Grand Duke Eric Lansmore is merely a cold stranger, and their forced political union is defined by a desolate silence. But a dangerous aphrodisiac shatters that distance, forcing them into each other’s arms for a night of unbridled desire. While Alexa fully expects a return to their distant routine, she finds herself completely overwhelmed by Eric’s terrifyingly intense affection. Her indifferent companion is now replaced by a desperately needy lover. (Source: Tappytoon)
